This open access book examines timely issues of integrated, international, and harmonized longitudinal research on child development and wellbeing. It describes the unique approach of the Growing up in Digital Europe (GUIDE) study, which is rooted in robust scientific inquiry and provides a solid evidence base for researchers, practitioners, and policy makers focused on child development in a digital world. Chapters employ a parallel structure, including background on each GUIDE topic as well as a summary of the current state of, future directions in, and recommendations for additional research. The book offers several select case studies that provide synergy and coherency across the chapters.

Key areas of coverage include:

• Holistic understanding of child wellbeing.

• Cross-national harmonized questionnaire development.
• Potential for data linkage and biological data.
• Ethical considerations in an age of digital data.
